Particle model of matter

Question 1

How does particles in a gas get energy?

Answer 1

Particles in gases gain energy from collisions with the walls

Question 2

How do we increase the energy in particles in a gas?I

Answer 2

Increasing the temperature increases the energy in a gas, meaning there are more collisions

Question 3

How can get a gas get low and high pressure?

Answer 3

Less collisions = Less energy = Low Temp = Low pressure + Lots of collisions = lots of energy = high temp = high pressure
